The injury occurred during a 45-20 win for the Welsh region at the Liberty Stadium.

The Fijian winger suffered the injury following a direct impact just minutes after replacing Jeff Hassler, and was forced off the field and taken straight to hospital.

"Aisea had an operation at the weekend and will have the injury reviewed at the end of this week after it has settled down, at which point we'll be in a better position to give a possible timeline for a return to play date," said Medical Performance Manager, Chris Towers.
